Interand intraspecific crossbreeding experiments were conducted to evaluate the aquaculture potential of hybrids in the genus Dicentrarchus, focusing on fertilisation and hatching success. The experimental design consisted of 24 controlled crosses in which individual and pooled fertilisations were made between wild D. labrax individuals (8 dams and 5 sires originating from West Mediterranean an...

Haldane’s rule of speciation states that sterility or inviability affects the heterogametic sex inter-species hybrids. Darwin’s corollary to implies there are asymmetric phenotypes in hybrids from reciprocal crosses. Studying F1 among closely related species malaria mosquitoes can assist researchers identifying genetic factors and molecular mechanisms speciation. To characterize sterile hybrid ...

We previously selected a line of the malaria vector mosquito Anopheles stephensi refractory (resistant) to the human malaria parasite Plasmodium falciparum, using in vitro infections with P. falciparum gametocytes. This report presents data on the genetic background of refractoriness. The results of F1-crosses and backcrosses show that refractoriness to P. falciparum in our A. stephensi line is...

Hierarchical classification problems gained increasing attention within the machine learning community, and several methods for hierarchically structured taxonomies have been recently proposed, with applications ranging from classification of web documents to bioinformatics. In this paper we propose a novel ensemble algorithm for multilabel, multi-path, tree-structured hierarchical classificati...

The inheritance of morphology of the pectoralis major muscle in turkeys at 16 wk of age was studied in a randombred control line (RBC2), a subline (F) of RBC2 selected long term for increased 16 wk BW only, and F1 and F2 crosses of the F and RBC2 lines. Samples of pectoralis major muscle were obtained from 10 males and 10 females of each genetic group in a manner to avoid muscle contraction. Af...

The bioremediation of polluted groundwater and toxic waste sites requires that bacteria come into close physical contact with pollutants. This can be accomplished by chemotaxis. Five motile strains of bacteria that use five different pathways to degrade toluene were tested for their ability to detect and swim towards this pollutant. Three of the five strains (Pseudomonas putida F1, Ralstonia pi...
